Claim of US Patent No. 10,335,998

1. An additive manufacturing system, comprising:a platen having a top surface to support an object being manufactured;
a support structure;
a dispenser to deliver a plurality of successive layers of a powder on the platen, the dispenser configured to deliver the powder on the platen simultaneously in a linear region that extends and is elongated along a first axis;
an actuator coupled to the support structure to move the support structure along a second axis parallel to the top surface and perpendicular to the first axis; and
an energy source configured to fuse at least a portion of the powder on the platen;
wherein the dispenser and energy source are secured to the support structure such that the dispenser and energy source move as a single unit with the support structure over the platen along the second axis and such that the linear region sweeps along the second axis to deposit the powder along a swath over the platen to form a layer of powder.
